Knak now has the ability to automatically scan your emails for common mistakes that may affect email deliverability and performance.
To enable this feature in your Knak account contact support or your customer success manager.
Optimize will appear as a new tab in the builder.
Optimize will check for the following issues for emails:
Standard
Alt Text - Checks if Alt text is provided on images
Asset Translation - Checks if the translated variants are not out of date - if you update the text or style (color etc) in the base (english) asset, the translations are flagged as out-of-date until you re-translate from the base again.
Background Height - The section height is greater than 2050 pixels
Text Over Background Image - Checks to see if there is contrasting text over top of an image
Border Color - Checks to see the colors used will work with Dark Mode
Button Border - Checks to see if there's enough contrast on the border of the button
Button Links - Checks if all button links have URLs added
Button Over Background Image - Checks to see if there's a button over a background image as rounded corners will be square on Outlook

The optimize tab will show you all items and whether each item has passed, warning or failed. Every issue will have a high or medium impact.
If any item has failed you can select 'highlight' to view the section of the email that has issues or select 'edit' to be taken to the relevant section to review and fix.
Configuring the Optimize Tab
The tests under the Optimize tab can be configured so that a failed test will either produce a warning or completely block the email from being synced or downloaded.
With Alternate Text, you can set it to give a warning, ignore or error.
